Official WhatsApp for Mac desktop application allows you to stay in touch anytime and anywhere - whether on your phone or computer at home or work. The app itself is quite similar to Web app that was meant to be an extension of your phone: the app mirrors conversations and messages from your mobile device.
The app is available for OS X 10.9 and later and is synced with your mobile device. Because the app runs natively on your desktop, you'll have support for native desktop notifications and better keyboard shortcuts.
Just like WhatsApp Web, the new desktop app lets you message with friends and family while your phone stays in your pocket. The tool must be installed on your cell phone so you can use WhatsApp on your Mac.
Features and Highlights
Simple, Reliable Messaging
Message your friends and family for free. The program uses your phone's Internet connection to send messages so you can avoid SMS fees.
Groups to keep in touch
Keep in touch with the groups of people that matter the most, like your family or coworkers. With group chats, you can share messages, photos, and videos with up to 256 people at once. You can also name your group, mute or customize notifications, and more.
Keep the Conversation Going
With the tool on the web and desktop, you can seamlessly sync all of your chats to your computer so that you can chat on whatever device is most convenient for you. Download the desktop app or visit web.whatsapp.com to get started.
Speak Freely
With voice calls, you can talk to your friends and family for free, even if they're in another country. And with free* video calls, you can have face-to-face conversations for when voice or text just isn't enough. The app voice and video calls use your phone's Internet connection, instead of your cell plan's voice minutes, so you don't have to worry about expensive calling charges.
Security by Default
'Some of your most personal moments are shared on the tool, which is why we built end-to-end encryption into the latest versions of our app.' When end-to-end encrypted, your messages and calls are secured so only you and the person you're communicating with can read or listen to them, and nobody in between, not even Whats App for Mac.
Share Moments that Matter
Send photos and videos on the app instantly. You can even capture the moments that matter to you most with a built-in camera. With Whats App, photos and videos send quickly even if you're on a slow connection.
Document Sharing Made Easy
Send PDFs, documents, spreadsheets, slideshows and more, without the hassle of email or file sharing apps. You can send documents up to 100 MB, so it's easy to get what you need over to who you want.
Note: Requires a mobile phone that has the WhatsApp utility installed and 64-bit processor.
